NEUTRAL SIZING OF WHEAT STRAW PULP

摘要

The neutral sizing of bleached soda-AQ wheat straw pulp was studied in the sizing system with polyaluminum chloride -organic polymer /dispersed anionic rosin size (PAC-P/DRS). And the sizing effects of precipitant of three kinds of PAC-P were compared. The result shows: compared to PAC/DRS neutral sizing system, in the condition, of adding 10% calcium carbonate, the better sizing effect can be obtained with PAC-P/DRS; and the sizing degree with cationic PAC-P is better than that of anionic PAC-P.
